Define needed functions

Load and prep AcousticStudies

If already created, load an existing dets PAMpal AcousticStudy object for event processing. We need to load both the unfiltered dets and filtered detsFilt AcousticStudies.

# load existing dets AcousticStudy (created with 
# workflow_generate_acousticStudies.R)
# load(detFile)

86 events before filtering and 84 events after filtering.

Load reference spectra, if specified

Load the reference spectra for plotting, if set with refSpecList.

# refSpecList is specified in YAML params. Can be one or multiple species
# for single species specify as char string without quotations e.g., refSpecPc
# for multiple species, specify with call to R and c()
#     e.g., !r c('meanSpecGm', 'refSpecPc_LLHARP')

  refSpecs = list()
  for (rs in refSpecList){
    refSpecs[[rs]] = read.csv(file.path(path_to_refSpec, paste0(rs, '.csv')))
  }
}

Event summaries

Loop through each detection event (n = 84) create plots and a table of summary statistics for click and whistle detections. This process uses AcousticStudy objects that have detection data for each event, and also pulls information from the Pamguard binaries associated with each AcousticStudy.

Click plots (other than the SNR plot) only show clicks with SNRs >= 15 dB.
